"Fine, whatever," she mutters under her breath, rolling her eyes. "But don't expect me to make you happy-happy in return... I mean it this time!" She stomps her foot petulantly before flopping down on her bed with a sigh, already lost in thought about her new game and the money she just got.

"What?!" Steffy sits up indignantly. "No way! I already gave you what you wanted; now it's your turn!" She crosses her arms over her chest, glaring at El uniSono through the crack in her bedroom door. "Besides, taking off my underwear isn't part of the deal... Don't try to change things now."

I'm glad you liked the picture! It feels a little strange exposing myself like this, but somehow it also makes me feel really good about my body. Seeing your reaction helps too - I know you find me attractive, which is a major turn-on.

My breasts are pretty big when they're freed from a bra - full and round with pink nipples that stand out prominently against my pale skin. They jiggle slightly as I move, especially when I'm standing up like in the photo.

She glances at you out of the corner of her eye, a mischievous grin spreading across her face. "Oh, I don't know... You mean like this?" Without warning, she reaches down between her legs and starts rubbing herself through her panties. Her other hand covers her mouth as if to stifle a gasp, but you can still hear the moans escaping from her throat.

Her hips begin to move rhythmically, grinding against your bed as she gets more and more lost in the sensation.

She pauses for a moment, considering your request. Her cheeks are flushed and her breathing is ragged as she looks at you pleadingly. "Please?" she whispers. "I'll be quiet... I promise..." She bites her lip, looking so desperate and needy that it's almost impossible for you to resist.

Finally, you nod reluctantly, knowing where this is going.

"Okay, my love. Sleep tight."

"Love you too," she says softly as they both fall asleep. I think that sums up our sibling-in-love relationship quite nicely... For now, at least. We'll have to see how things develop further in the future. Thanks for reading! If you want to read more stories like this one, check out my other works listed below.

"Why, right here with you,"

She smiles up at him, tracing a finger along his jawline. With a sigh, she stands up from the bed, her body still flush from their lovemaking. Naked, she walks over to the dresser and opens one of the drawers, extracting a pair of lacy underwear. With a wink, she turns around to face him.

"Put these on, Daddy, I think they'll look good on you."

"Come on, just for fun. You know you want to try them on." Her voice is teasing, but there's an undeniable heat in her eyes. Slowly, Riley begins to unbutton his pants, revealing his hardening arousal beneath. He slides the underwear up his thighs before stepping into them, adjusting the waistband as he looks up at Steffy with a challenging grin.

"There. How do I look?"

Ahh! Ack! Sooo n-nasty... but so good... Faster, please... faster...

Ahhh! Ackkkk! D-Don't call me that... but yeah, I do... Fuck, it feels so good...
